In an interview with WGN Radio, Emanuel said city officials deserved to know exactly what happened the night of Smollett's alleged assault.
"He is charged with 16 counts for creating a hoax about a hate crime. He walks out, says, 'I'm innocent.' They say, 'No, he's guilty, and the police work is good,'" Emanuel said.
"Now, you can't be both on the same case. So to me, was he or was he not guilty of a hoax, or was there a hate crime committed? Yes or no, it's very straightforward," he added. "There's no sense of contrite [sic]. No remorse."
Emanuel went on to say that his office would direct the city's corporation council to analyze costs associated with the investigation and take action against Smollett.
"The police are right now finalizing the cost that was used of police resources to come to the understanding that, in fact, this was a hoax," he said.
"[We] will then send a letter to Jussie Smollett and his attorneys trying to recoup those costs," Emanuel said, adding that the actor's $10,000 bond didn't "even come close to what the city spent in resources."
Emanuel declined to say whether he would consider directing city attorneys to sue Smollett in court with the hopes of recouping the cost, though he did note that an attorney for the city considered Smollett's promise to complete community service as an admission of guilt in the matter.
Smollett told reporters this week at a press conference that he was innocent of the accusations after the charges against him were dropped.
“I would not be my mother’s son if I was capable of one drop of what I was accused of," he said. “I am a man of faith and I am a man that has knowledge of my history and I would not bring my family, our lives or the movement through a fire like this. I just wouldn’t."
